| Description | Superbubbles (SBs) are formed by the combined actions of stellar winds and supernova explosions from massive stars in OB associations. These objects contribute significantly to the hot gas component of a galaxy.s interstellar medium (ISM), as well as affecting the structure of the ISM to large scales. We propose XMM-Newton observations of two SBs in the Large Magellanic Cloud, N70 and N185, with indicators of recent interior SNe. From their X-ray spectra, we will investigate (a) enhanced abundances indicating recent enrichment by SN ejecta; (b) the energy budgets of the SBs, and whether those are consistent with expected stellar-wind inputs; and (c) the required input of SNRs to these SBs to obtain the observed energies. |

| Mission Description | The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis. |
